7 1o (1U/whom t may concern:

Be it known that I, MARTiN B. MA'rTsom a Citizen of the United States,residing at Princeton, in the county of Millelacs and State ofMinnesota, have invented new and useful Improvements which the followingis a specification.

This invention relates to bog shoes for horses or similar draft animalsand it consists in the novel features Vhereinafter described andclaimed.

An object of the invention is to provide a bog shoe such as may beapplied to the shoe of a horse when the animal is used upon soft ormarshy ground and a further object of the invention is to provide such ashoe which may be easily and quickly adjusted to t the foot of theanimal.

With this object in view the shoe comprises a board having means forIretaining the rear portion of the shoe which 1s .permanently iXed to thehoof of the animal and means adapted to be passed over the upper forwardportion of the hoof whereby the board is held in position belowthepermanent shoe.

In the accompanying drawing Figure 1 is a side elevation of one form ofthe shoe showing the same applied.

Fig. 2 is a top plan View of the form of shoe shown in Fig. 1.

The shoe includes a board 1 which is preferably of wood or .othersuitable light material. A lug 2 is mounted upon the upper surface ofthe board 1 in the vicinity of one side edge thereof and a similar lug 3is mounted in the vicinity of the opposite side edge of the said board.YThe said lugs 2 and 3 are provided with a series of perforations 4which are adjusted to receive bolts 5 whereby metallic strips 6 areadjustably connected with the said lugs. The bolt 7 passes transverselythrough the free end portions of the strips 6 and is adapted to securethe free end of the strips together over the upper forward portion ofthe animal. The board 1 is provided at that side portion upon which thelug 3 is mounted with a series of perforations 8 adapted to receive thebolt 9 which secures the lug 3 to the board. Thus it is possible toshift the lug 3 transversely of the board 1. The lug 2 is secured to theboard 1 by means of a bolt similar to the bolt 9 hereinbefore described.These bolts pass transversely through the board 1 and t rough ametalli@- in Bog-Shoes, ofk

' provided at one end strip 10 which is positioned against 'the lowerside of the board 1. The board 1 is provided at its upper` side and'inthe vicinity of its rear edge with a transversely disposed channel v11which receives the body portion'of a bar 12. The said bar 12 is with anupstanding lug 13 which is disposed at an acute angle with relation tothe median longitudinal dimension of the bar 12 and which is adapted tobear against the outer side of one heel portion of the permanent shoe ofthe animal. The bar 12 is provided in the vicinity of that end oppositethe end at which the lug is located with a series of perforations 14.The board 1 is provided at the forward edge of the channel 11 and nearthe perforations 14 with a recess 15 which enters the said channel 11. Abolt 16 passes through one of the perforations 14 and transverselythrough the board 1 and also passes through the base portion 17 of a lug18 which is adjustably mounted upon the bar 12. The lug 18 is disposedat an acute angle with relation to the median longitudinal dimension ofthe bar 12 and is adapted to bear against the outer edge portion ofoneheel of the permanent shoe of the animal.

The base portion 17 is provided with a downwardly disposed flange 19which is received in the recess 15. Therefore it will` be seen thatmeansare provided for shift-V ing the base 17 with relation to the lug 13 andthe flange 19 prevents the lug 18 from turning after it has been fixedat an adjusted position under the bar 12'. A bolt 20 passes transverselythrough the bar 12 and also the board 1 and the bolts 16 and passtransversely through a strip 21 which is positioned against theunderside of the board 1. The strips'lO and 21 are disposed tranverselyof the grain of the board and prevent the same from splitting when thedevice is in use.

The lugs 3 and 18 are adjusted transversely of the board 1 to fit thefoot or hoof of the animal and when the heel portions of Copies of this'patent may" b e obtained for ve cents each, by addressing the atv oneend an upstanding lug, said bar being provided in the vicinity of itsother end With a series of perforations, a base member mounted upon thebar, a bolt passing through the base member and one of the perforations,said base member having an npstanding lug, the base member being'further provided vvith a flange Which bears against the edge of the barand lies in the said recess.

In testimony whereof l. afiiX my signature.
